SNAP-HOOK.

SPECEIFIGATION forming part of Letters Patent No. 416,453, datedDecember 3, 1889.

Application filed May 1, 1889. $erial No. 309,297. -(No model.)

To all whom it may concern:

Be it known that I, OTTO FLEISOHHAUER, a subject of the King of Saxony,German Empcror, and a resident of the city of Berlin, in Prussia,Germany, have invented certain new and useful Improvements inSnap-Hooks, of which the following is a specification.

This invention relates to improvements in snap-hooks such as are usedfor connecting watch-chains with watches, lockets, &c., or for holdingtrinkets, for holding bands in button-holes, straps 011 rings, (to.

The object of my invention is to provide a snap-hook which is simple inconstruction and which holds and locks the article securely.

The invention consists in the construction and combination of parts anddetails, as will be fully described hereinafter, and finally pointed outin the claims.

In the accompanying drawings, Figure l is a vertical longitudinalsectional view of my improved snap-hook closed. Fig. 2 is a face View ofthe same open. Fig. 3 is a face view of the same closed and a ring heldin the snap-hook. Fig. 4 is a face view of the same, showing the sameopen and in position for moving the ring to the upper part of the hook.Fig. 5 is a faceview of the same, showing a number of rings held on bothparts of the snap-hook. Fig. 6 is a face view of a modified constructionclosed. Fig '7 is a face view of the construction shown in Fig. (5opened. Fig. 8 is a cross-sectional view on line a; 00, Fig. 1. Fig. 9is a cross-sectional view on line Q/ g, Fig. 1. Fig. 10 shows thesnap-hook secured to a band and holding a number of trinkets. Fig. 11shows the snaphook held in a button-hole.

Similar letters of reference indicate corre sponding parts.

The snap-hook is composed of two main parts A and B, the former beingmade of wire and the latter of a piece of circularly-bent tubing. Thewire forming the part Ais bent to form a frame having the tops inclinedtoward each other and then bent upward and outward to form a segmentalcurved short shank b and a larger shank a, said shanks a and I) beingcurved on the same center. Be-

tween the lower ends of said shanks the openlng e e is formed. Thetube-shaped part B consists of a tube 1 of such diameter that the shanksa and b can pass into the same, said tube being curved on the sameradius with the shanks a and b. At one end the tube is provided With acurved arm d, which connects it with another tubular piece or arm 0,

curved on the same radius as the tube 1" and the shanks a and b. Thepiece 0 is provided with a slot 0 of sufficient width to permit theshank a to pass. A collar A is secured to the free end of the curvedtuber, and a spiral spring f is contained Within the curved tube r, oneend of said spring resting against the end of the shank a and the otherresting against the fixed lug of the piece a in the tube 1', whichspring has the tendency to keep the parts in the position shown in Fig.1.

When it is desired to apply a ring 0 on the snap-hook, a finger isplaced against the fixed collar A and the same pressed in the directionof the arrow 00, Fig. 1, whereby the curved tube will be moved in thesame direction and the curved arm d and short tube 0 brought into thepositions shown in Fig. 2, the short curved tube 0 being 011 the shankb. The curved arm d forms a recess into which the ring 0 can be placed.

lVhen the curved tube r is released, the expanding spring f throws it ininverse direction of the arrow 00 and brings the parts back into theirnormal position, (shown in Fig. 1,) and thereby the ring 0 is carriedthrough the top opening of the bottom part of frame A of the snap-hook,as shown in Fig. 3. In case it is desired to bring this ring into theupper part B of the snap-hook, the collar A is again pressed down so asto bring the part B into the position shown in Figs. 2 and 4, and thenthe ring is moved upward, as indicated by the arrow 00 in Fig. 4, andthen the collar A released. rings may be brought into the "upper part Bor lower part A of the snap-hook, as shown in Fig. 5. A numberoftrinkets can be held on the part B of the snap-hook, asshown in Fig. 10,and the snap-hook can be passed through a button-hole, as shown in Fig.11.

If desired, the parts may be reversedthat is, the bottom part A may bemade integral with a curved tube A adapted to receive a curved wire at,having the bend d and the shank b, the bottom part A being provide Inthis manner any number of ICO with a short bent tube 0. This device isopened by pushing the bent wire a into the curved tube a, as shown inFig. 7. The ring to be secured to the snap-hook is then placed into therecess formed by the bend d and the wire a pushed back into the positionshown in Fig. 6.

This snap-hook is composed of few parts, is very simple and very secure,and forms a double lock, which is a very essential feature.

Having thus described my invention, I claim as new and desire to secureby Letters Pat-en t- 1. A snap-hook composed of a main frame having twocurved shanks and a tubular sliding piece curved on the same radius asthe curved shanks and adapted to slide on said shanks, which slidingpiece is provided with a curved part or arm forming a recess,substantially as set forth.

2. A snap-hook composed of a main frame having two curved shanks and atubular sliding piece curved on the same radius as the 5 curved shanksand adapted to slide on said shanks, which sliding piece is providedwith a curved part or arm forming a recess, and a spring inclosed insaidtubular piece and acting on the sliding part, substantially as setforth.

3. A snap-hook composed of a main frame having two circularly-curvedshanks of different lengths, a tubular sliding piece curved on the sameradius as the shanks of the main frame and adapted to slide on saidshanks of the main frame, which sliding piece consists of two curvedshanks connected by a bent arm or part forming a recess, and a springinclosed in said tubular piece, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
